Product details
Overview
TLC2274AQDRQ1 from Texas Instruments is a quad, rail-to-rail output, LinCMOS™ operational amplifier qualified to AEC-Q100 Grade 1 (–40°C to 125°C), with 2.2 MHz gain-bandwidth product, 3.6 V/μs slew rate, and 9 nV/√Hz input voltage noise at 1 kHz. It supports single- or split-supply operation up to ±8 V and delivers rail-to-rail output swing for interfacing with precision ADCs in automotive signal conditioning.
For engineers reviewing the TLC2274AQDRQ1 datasheet, TLC2274AQDRQ1 pinout, TLC2274AQDRQ1 application, or TLC2274AQDRQ1 equivalent, this page provides verified electrical specifications, automotive-grade thermal and ESD performance (HBM ±2000 V), functional safety documentation support, and validated alternatives for body control modules, battery management systems, and engine control units.
Technical Context
The TLC2274AQDRQ1 implements a CMOS-input, rail-to-rail output architecture optimized for low-noise, high-impedance sensor signal conditioning in automotive environments. Its input stage features 1 pA typical bias current and 10¹² Ω common-mode input resistance, enabling stable operation with piezoelectric transducers and resistive sensors.
It operates across ±2.2 V to ±8 V supply ranges, maintains rail-to-rail output swing down to 20 μA load, and achieves 75 dB typical CMRR and 95 dB typical PSRR - critical for noise-sensitive analog front-ends in electric power steering and inverter control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports dual-rail automotive systems (e.g., ±5 V) and single-rail 5 V microcontroller interfaces |
| Gain-Bandwidth Product | 2.25 MHz - enables stable closed-loop operation up to ~200 kHz with moderate gain (e.g., AV = 10) |
| Slew Rate | 3.6 V/μs - ensures <2.6 µs settling to 0.01% for 4.6 Vpp step, suitable for fast transient monitoring |
| Input Offset Voltage (max) | 950 µV - specified over full temperature range for TLC2274A-Q1 variant, enabling <0.1% error in 1 V full-scale measurements |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - two times lower than competitive CMOS op amps, reducing integrated noise in 10 Hz–100 kHz bands |
| ESD Rating (HBM) | ±2000 V - AEC-Q100-002 Level 2 qualification ensures robustness during automotive PCB handling and assembly |
| Operating Temperature | –40°C to +125°C - qualified for under-hood and transmission control unit placement without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434-Q1 | Lower supply current (1.2 mA/ch vs 1.5 mA/ch), but reduced GBW (1.4 MHz) and higher VIO (1.5 mV max) | Better suited for ultra-low-power body electronics; less ideal for high-speed current sensing | Select when power budget <3 mA per channel dominates; avoid for >100 kHz closed-loop bandwidth needs |
| LMV884QMA/NOPB | Higher slew rate (10 V/μs), wider supply range (2.7–12 V), but no AEC-Q100 Grade 1 rating and higher noise (17 nV/√Hz) | Used in industrial motor drives; not qualified for automotive under-hood deployment | Choose only for non-automotive designs requiring faster response; verify thermal derating above 85°C |
Compared with TLV2434-Q1 and LMV884QMA/NOPB, the TLC2274AQDRQ1 uniquely balances AEC-Q100 Grade 1 qualification, 9 nV/√Hz noise, and 2.25 MHz bandwidth - making it the preferred choice for ASIL-B-compliant automotive signal chains where precision, speed, and reliability are jointly constrained.

FAQ
What is the maximum supply voltage for TLC2274AQDRQ1?
The TLC2274AQDRQ1 supports absolute maximum supply voltages of ±8 V on VDD+ and VDD– terminals. Operation beyond this risks permanent damage. For reliable long-term use, TI specifies recommended operating conditions of ±2.2 V to ±8 V - meaning the TLC2274AQDRQ1 can safely run at ±5 V, ±3.3 V, or single 5 V with VDD– tied to ground. Derating is not required within this range.
Does TLC2274AQDRQ1 support single-supply operation?
Yes, the TLC2274AQDRQ1 fully supports single-supply operation. With VDD– connected to ground and VDD+ at 5 V, its common-mode input range extends from ground (VDD–) to VDD+ −1.5 V (3.5 V), and its output swings rail-to-rail from near 0 V to near 5 V. This enables direct interfacing with 5 V ADCs and microcontrollers without level-shifting components.
Is TLC2274AQDRQ1 pin-compatible with TLC2274QDRQ1?
Yes, TLC2274AQDRQ1 and TLC2274QDRQ1 share identical pinout, package (SOIC-14), and electrical interface. The "A" suffix denotes tighter input offset voltage specification (950 µV max vs 2500 µV max), but all pins - including VDD+, VDD–, and all four channels' inputs/outputs - are functionally and physically identical. No PCB redesign is needed when upgrading.
What functional safety documentation is available for TLC2274AQDRQ1?
Texas Instruments provides functional safety documentation for the TLC2274AQDRQ1, including FIT rate data, failure mode effect analysis (FMEA), and diagnostic coverage guidance - specifically referenced in the device's product folder and functional safety manual. This documentation supports ISO 26262 ASIL-B system-level development but does not constitute full ASIL-B certification of the IC itself.
Can TLC2274AQDRQ1 drive a 10 kΩ load at full rail-to-rail swing?
Yes, the TLC2274AQDRQ1 delivers rail-to-rail output swing into 10 kΩ loads. At ±5 V supply and 25°C, VOH = 4.85 V (min) at –200 µA and VOL = –4.85 V (min) at +200 µA - representing >97% of full scale. Performance remains stable across temperature; at 125°C, minimum swing degrades to ±4.25 V at ±1 mA, still sufficient for most 12-bit ADC interfaces.
